The SerTech Labs
STELLAR XII
is a three-way, front firing,
high-efficiency
speaker system that has proven incomparable,
above all others!

These speakers provide absolute superb frequency response.
They provide
full room volume
with only 1 watt of power, and produce
excellent fidelity with as little as
1/10th
watt.

Four high-output wide-range alnico magnet tweeters are used to provide a
crystal clear, smooth
response that is a pleasure to listen to for long
periods of time. The mounting arrangement is a short line source vertical
array of tweeters. This gives greater power handling, more output,
and
superior horizontal dispersion.
It seamlessly integrates with the
midrange driver much more effectively than a single tweeter system.
A fourth
ambiance tweeter is mounted in the rear.

The bass driver is a
12" fast acting
woofer with a specially treated non-deteriorating fabric accordion
surround edge. It uses a quick response flat progressive spider assembly,
all mounted in a die-cast aluminum frame. The bass output of these woofers
will easily out-perform 10", 12" and most 15" powered subwoofers with
as little as 8 watts.

The crossover is
custom made
and tuned to give the proper
"SAR"
to each driver. It uses only one pure
copper inductor and one high quality capacitor for each driver. This
method keeps efficiency high and phase shift distortion to a minimum.
This system provides good amplifier matching without excessive
capacitive or inductive loading. Both the tweeters and midrange have
controls that are
infinitely adjustable
from 0 level to full output.
These controls are part of the
Smooth
Adjustable
Response
crossover system.
